One of those guys, usually in their forties, who wear blinking bluetooth ear pieces all the time, everywhere. When looking at them, it is impossible to tell if they are talking to you or some other earplant on their phone. Earplants tend to be nerdy, corporate wannabees, and they think that the bluetooth headset makes them look professional. Well, news flash: it doesn't. It is just annoying.

Johnny: Why the fuck is your dad on the phone during our high school graduation?
Sammy: Shut up, Johnny. He's just an earplant; he wears that thing all the time, even when he isn't on the phone.
